脑-肠互动紊乱是肠易激综合征(irritable bowel syndrome, IBS)发病的重要原因,但其脑功能动态特性仍不清楚。本研究针对以往基于功能磁共振成像的脑网络动态分析的缺点,提出一种基于逐时间点斜率分析的动态特性度量方法,以此来检测IBS患者脑功能动态异常变化情况。结果表明,与健康被试相比,IBS患者脑活动及功能连接均发生一定程度的改变。在经过FDR (false discovery rate)校正之后,只有右侧后扣带-左侧额中回、右侧后扣带-左侧苍白球这两条功能连接上表现出显著的动态特性异常,该结果与IBS患者的静态特性存在较大差异。以上结果为阐明IBS异常的机制提供了互补信息,可为IBS中枢靶点的揭示提供新的方向。

股权众筹作为资本市场中一种重要的融资形式已越来越为投资者们所关注。作为一种全新的金融业态,股权众筹模式自国外引进后,虽然在国内进行运作时已经做了中国式改良,但目前仍缺乏基本的法律制度体系构架,特别是在行业规范、风险防控和投资人保护等方面存在制度缺失的情况。以中国式股权众筹融资模式及其交易流程为讨论对象,对股权众筹交易中不同主体所面临的风险进行深入分析,是设计有效的风险防范措施、构建完善的股权众筹监管体制,引导股权众筹良性发展的必要前提。
